Daniel Henrique Barboza b748352c55 hw/riscv/virt.c: move create_fw_cfg() back to virt_machine_init()
Commit 1c20d3ff60 ("hw/riscv: virt: Add a machine done notifier")
moved the initialization of fw_cfg to the virt_machine_done() callback.

Problem is that the validation of fw_cfg by devices such as ramfb is
done before the machine done notifier is called. Moving create_fw_cfg()
to machine_done() results in QEMU failing to boot when using a ramfb
device:

./qemu-system-riscv64 -machine virt -device ramfb -serial stdio
qemu-system-riscv64: -device ramfb: ramfb device requires fw_cfg with DMA

The fix is simple: move create_fw_cfg() config back to
virt_machine_init(). This happens to be the same way the ARM 'virt'
machine deals with fw_cfg (see machvirt_init() and virt_machine_done()
in hw/arm/virt.c), so we're keeping consistency with how other machines
handle this device.
